Stephen Marshall designs and builds tiny homes on top of a flatbed trailer, then rolls them out to his client's site. The homes are "Park Model Recreational" units or more bluntly put: trailer homes. Marshall explains that "unlike most RV's or mobile homes, [these homes are] built with traditional techniques at a level of craft found only in high end custom construction..."

Although Marshall's company, Little House on the Trailer, custom designs each space, they offer three types of structures up to 400 square feet: dwellings complete with kitchen and bath, offices, and art galleries.

Structures are fully insulated and plumbing is ready for hook-ups. Prices vary according to the order, but the dwelling (shown here) is $65,000, the one-room office (shown in the first photo) is $55,000 and the art studios (shown in the last two photos) are $45,000.

Based in Northern California, Marshall delivers the trailer homes at the rate of $5.00 per mile. Unlike RVs, these homes are intended to stay in one place, although their trailer bed construction makes them portable in the case of a move.
